Read the full story on Japan 2 Earth – Groundbreaking green hydrogen system to drive decarbonization
On August 6, trial operation of the green hydrogen production system led by Yamanashi Prefecture began. Unit 1 of the Yamanashi model power-to-gas (P2G) was put into trial operation at a concrete component factory in Kawagoe City, Saitama Prefecture. This is the first installation of a green hydrogen production facility at an existing factory in Japan.
The system is designed to support the transition from fossil fuels such as town gas and heavy oil to green hydrogen. Since green hydrogen does not emit carbon dioxide (CO2), it is linked to decarbonization efforts. Yamanashi Prefecture is a leader in promoting P2G technology, with plans to roll out one of the world’s largest P2G systems.
Use as heating fuel
The system was introduced at a factory of Taisei U-Lec in Kawagoe. Taisei U-Lec, a subsidiary of the major Taisei Corporation, manufactures concrete structural components. The PEM-P2G system was jointly developed by Yamanashi Prefecture, Toray, TEPCO Energy Partner and others. A small 500-kilowatt model is already in operation.
The P2G system electrolyzes water and produces hydrogen using electricity generated by a 1 MW solar array on the factory’s roof. This hydrogen is used as boiler fuel to generate steam. This heat is then used in the curing process to accelerate concrete hardening.
